I have settled on 90gr. 777, and a 295gr. powerbelt. Terrific on whitetails for me. I would also advise if using scope to get quick detachable rings.
Makes cleanup easier. In fact I clean like a regular rifle.. no water,
and never any crud or sign of corrosion / rust. Rub light machine oil
(Singer, or any name gun oil) on whole barrel assembly, and I'm ready for the next hunt. Am I the only without the bucket of hot soapy water?
